我是这个怪异的Maven事物的新手，不确定它是如何工作的。我的项目包含一个有效的pom.xml文件，但我无法对其做任何事情。基本上，我转到File -> Project Structure -> Libraries -> From Maven...并在此搜索字段中编写pom.xml，但找不到任何东西！我很确定我做错了什么。通常，我只想知道如何将所有库下载到.jar格式中。我使用IntelliJ，我的pom.xml看起来像这样：

预先感谢您。
有很多事情可能会发生在这里，但先尝试一下：
尝试ctrl-shift-a->"重新竞争所有Maven Projects"
或
视图 ->工具窗口 -> maven项目 ->单击左上按钮(看起来像一个刷新图标(
首先确保您的项目使用Maven？！也许它正在使用gradle，所以在
上对于Maven项目，POM.xml文件：
对于Gradle项目，build.gradle文件：
Apache Maven的替代方案。Jira，Jenkins，Gradle，Apache Ant和Apache Tomcat
右键单击POM，选择Maven，然后选择Unignore Project
